I have been building websites for a long time, and I have definitely encountered the situation where the website was k, which caused these situations to be brushed against each other in the industry. There are also some malicious means to attack the website. You must first analyze the reasons for being k, such as being linked to a black chain, or some other irregular operations. The following Huaian website construction company specifically analyzes the reasons that lead to being k.
1. The website is hacked
Hacked links on websites are generally related to the website's programs and the security configuration of the server. Once the website is linked, the search engines believe that the website will have a certain "access risk". In order to avoid losses for other users, this website will Delegation processing. Therefore, the way for webmasters to avoid being hacked is to regularly go to the official website program to see if the program's release dynamics issue new patches and update the website vulnerabilities in real time. As long as the patch is fully applied, the security of the website can be improved by 90%.
2. Website over optimization
This situation should be the reason for most of them being k, and it is also the situation that novices who just started working in SEO do not understand. There are many newbies who always like to optimize the site to the "extreme" anywhere, and do everything perfectly. In fact, this is a wrong method, which will lead to over-optimization. Changes to the website many times, such as changing the title of the website, this change for Baidu is the same as changing the name of the website and requires re-understanding. At this time, the ranking of the website will drop, so do not easily modify the title of the website.
3.Search engine updates
Each search engine update will cause a large number of website rankings to drop. The reason for this is that Baidu Update will eliminate a batch of low-quality sites. However, the SEO Forum feels that there will be some “mistakes” in the algorithm update. No one algorithm can be 100% accurate. So it will cause a batch of website rankings to drop. Do n’t rush to modify something at this time, it may be restored after a while.
4.Low quality external chain
Before Baidu had not updated the external chain algorithm, it was possible to send some external links, and being a friend chain website would rank up, but now it is not working. The current external chain is about extensiveness, authority and stability. If a large number of external links are posted on a platform, it is very dangerous, and now it should be built for the construction of high-quality external links.
5. Stability of website server
The stability of the server is also very important. The stability of the server determines the development of this website. Many people think that the initial cost will be relatively high and they will choose the first cheap space to put the website on the website. After that, the server's IP may be attacked. The idc service provider will find various reasons such as what is being maintained. If the maintenance is not performed for a period of time, the current host IP will be resolved. This is the factor that causes the website to be degraded.
A DDOS attack is to combine multiple computers into an attack platform and launch a DDOS attack on a site at the same time. As a result, the website cannot be accessed and the access times out. At this time, the impact on the website is very large. When the spider crawled the website, a large number of 404 error return codes appeared. The spider will judge that the website is unstable, which will affect the user experience. In this case, the search engine will degrade the website.
